The article is devoted to bearing analysis, which has a specific shape. The outer ring is the body directly and the inner ring is the case. To determine optimal radial clearance or overlap are used the thermal / structural analysis. The article is logically divided into two parts. In the first analysis, was monitored the impact of the press-fit of the case into the body. In the second analysis, there are presented attained results in graphical outputs of displacements in the orbits at different operating temperatures. At the end of the article were evaluated and researched individual effects on bearing deformation.

The aim of the article is to point out the sealing efficiency of the two-language seal of the water pump bearing when radially deflecting the shaft within radial clearance. In order to obtain a radial displacement of the shaft at a location under a two-language seal, dynamic bearing simulation was performed using the MSC Adams program. The largest radial deviation of the shaft was applied in final seal analysis where the contact pressure changes on the individual tongues of the seal were recorded.

The objective of these analyzes is to evaluate the behaviour of bearing cage in operation and to determinate the safety factor towards to yield and ultimate strength of structure, when cage is under load. Safety factor can be defined as force needed to achieve yield or ultimate strength divided by operation force given from dynamic simulation. Second analyze was based on pressing of whole cage in radial direction to determinate radial pressing force needed to achieve yield and ultimate strength.
